EchoMem MCP bridge for cross-agent memory, local history import, and recall
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo malicious npm lifecycle behavior or covert install-time control-surface mutation was found. The persistent hooks, automatic runtime updates, and conversation-ingestion capability warrant a warning for agent-extension lifecycle risk.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs init, setup, or update, then starts an agent session or invokes an EchoMem memory operation.
Impact
Future agent sessions can execute the package command; saved conversation content can be transmitted to the EchoMem service.
Mechanism
Persistent agent hooks, background self-updating runtime, and remote memory ingestion.
AI rationale
No malicious npm lifecycle behavior or covert install-time control-surface mutation was found. The persistent hooks, automatic runtime updates, and conversation-ingestion capability warrant a warning for agent-extension lifecycle risk.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The running MCP checks for updates and automatically stages a newer release in the background.
- Explicit setup installs commands into Codex and Claude lifecycle-hook configuration.
- A memory-save operation sends supplied conversation data to the EchoMem API.
Evidence against
- package.json has no preinstall, install, or postinstall script.
- The nested runtime installer uses npm with --ignore-scripts.
- Configuration changes are reached through explicit init, setup, or update commands, not package installation.
- The HUD binds its HTTP server to loopback.
